What are the reasons for the jerking of Geely Emgrand at low speed?

Geely Emgrand car jerking at low speed may be caused by: too much carbon deposits, insufficient fuel combustion, spark plug failure, etc. Normal situations with jerking: For manual transmission models, when driving in a semi-clutch state, both accelerating and decelerating will produce a jerking sensation. The deeper the throttle is pressed, the stronger the jerking sensation; For automatic transmission models, there will be a slight jerking sensation when accelerating and shifting up, and it will be more obvious when forcing downshifting and then upshifting with a large throttle. Differentiation of car jerking: Jerking can be divided into occasional and fixed-time. Occasional jerking occurs without any pattern, while fixed jerking occurs when reaching a certain speed or shifting from a certain gear to another (e.g., from 2nd to 3rd gear) at a fixed speed. The reason for car jerking is that there is sludge in the transmission oil circulating and blocking the oil passages in the valve body, which will lead to jerking problems. Over time, it will cause a series of transmission problems such as high temperature, impact, and slippage.
When I noticed my Geely Emgrand jerking at low speeds, I thought it was usually caused by the transmission not shifting smoothly in low gears. Some of the dual-clutch designs used by Geely are prone to shaking at low speeds, possibly due to unstable oil pressure or the need for a software update to the shift logic. Additionally, engine carbon buildup can cause issues with the ignition system, and poor fuel quality can lead to unstable combustion. I've experienced similar situations before, and after inspection, replacing the spark plugs and cleaning the throttle body made it much smoother immediately. I recommend developing a habit of servicing your car every six months, such as using fuel additives to clean carbon deposits and ensuring timely transmission oil changes. Don't underestimate such minor jerking—over time, it can accumulate and damage the drivetrain, affecting the vehicle's lifespan. Addressing it early ensures peace of mind and prevents potential issues during city traffic jams.
Driving the Emgrand at low speeds is really annoying with all that jerking, always stuttering before traffic lights. I found this is often due to transmission control issues. Geely's dual-clutch transmission isn't very responsive at low RPMs, and perhaps excessive engine carbon buildup is affecting power delivery. Aging fuel pumps or clogged air filters can also cause insufficient fuel supply, leading to unsteady driving. Later, I took it to the shop for inspection, and they simply replaced a sensor to fix it. Remember, start smoothly without stomping on the throttle too hard to reduce the jerking. Maintenance-wise, it's recommended to clean the fuel injectors and throttle body once a year—saves money and hassle. Always pay attention to your vehicle's condition to avoid sudden breakdowns on the road.
